Hearing Boss Luo's introduction, the crew all nodded, they all know this situation, Xiao Fei currently has two studios, one is engaged in radio on the top floor of the Red Mansion, and there are also here to tinker with all kinds of wired and wireless communication equipment, it is said that he made a vacuum tube as big as a water cup in the glass factory a while ago, obviously he is going to go to the road of electron tubes, although the vacuum tube made is very thick, and the internal space is also very small, but after all, it can be regarded as a major achievement......

However, everyone didn't see him for a while, and they couldn't ask for more specific content, so Boss Luo went on to say that Xiao Fei had been very busy in the past two days, and he was probably wiring outside with a few science and engineering men.

Looking at everyone with a confused face, Boss Luo explained that Xiao Fei has been busy installing a two-way wired communication system these days, which is a quasi-"telephone broadcasting" system, in fact, it is a wired walkie-talkie, you only need to turn on a switch, press the button, you can connect to the distant speaker call, so as long as the speaker is installed, you can hear the speech on that side, and this is two-way, although this design is a bit simple, but it has a good communication effect, Boss Luo believes that Xiao Fei, a young man, It is quite good to be able to do this under the existing conditions.

The crew listened to it and said that they understood, this kind of communication system is on the Nicole, and we have a speaker box in each cabin, Nima every morning, Xu Damate is in the speaker box and shouts to everyone to get up, or else play music, forcing us to get up, the key is that this horn has not been switched on and off, but it is one-way, and the crew in the cabin is forced to listen until we are completely awakened......

Boss Luo went on to say that Xiao Fei plans to use this communication system to connect the slipway at the Red Wharf, several Manshui Dam hydropower stations, and several factories in the Xiliuhe Industrial Zone in the near future.

However, in order to save lines, these channels are public, and there is no dedicated independent line in each place.

This means that you can press a button anywhere and you can hear it everywhere else, but there's no way around it, and everyone understands that wires from the old world need to be used sparingly.

Hey, according to the existing conditions, there is still a long way to go before our metallurgical industry can independently produce metal wire.

Boss Luo sighed after saying this......

So, everyone talked all the way and soon arrived at the gate of the half-open cave.

Out of the gate of the cave, there is the small square that was built as early as the burning period, and now, the ground of the small square has long been hardened with cement.

A railway line embedded in the concrete floor extends from the cave gate to the distance.

On both sides of the small square are rows of huge bamboo greenhouses, which are Lao Wang's vegetable garden experimental sheds, where various crops and vegetables are grown, and where there are now a permanent few female laborers responsible for daily maintenance.

Further south to the end of the small square, on the edge of the Red Hole Line of the railway, is the factory area of Boss Luo's mechanical maintenance factory and glulam factory.

Because the "technical content" of these two factories is relatively high, Boss Luo can't find a few satisfactory operators among the 400 Han men and women, so there are only five "temporary workers" in the factory who are helping the members of the mechanical team to do some simple manual work such as handing tools, carrying, cleaning and cleaning.

As soon as everyone entered the bamboo greenhouse of the machinery maintenance factory, they saw a furnace and a pool, Boss Luo explained, this is the heat treatment equipment moved out of the cave, the furnace can be calcined and annealed, as for the small pool made of cement, it is a quenching pool, Boss Luo said and also opened the lid on the small pool, which is a turbid milky white unknown liquid.

"It's our homemade improvised quenching fluid."

At this time, Boss Luo's tone was full of pride.

Then, the young people's eyes were quickly drawn to the two rows of machine tools in the greenhouse.

The row of machines in front of you is clearly from the old world, with turning, milling, grinding drills and all kinds of tooling.

However, there is a bit of a strange row in the back, where there are two lathes and two drilling machines, apparently finished products, and next to it, there is a row of semi-finished products, some of which are just pedestals, and it seems that these are some of the gold processing equipment in the making.

However, the four completed machines are obviously much rougher and more rudimentary, and the most bizarre thing is that the bases of these machines are actually made of bricks and cement!

Well, everyone has heard Boss Luo talk about this for a long time, and everyone thinks that it is a very strange practice, but now it has become a reality in front of them!

At this time, Boss Luo proudly introduced that these machine tools are the "quasi-second generation" machine tools we made, and the reason why they are said to be the quasi-second generation is that these equipment are indeed produced by machine tools brought by the old world, but some materials are no longer from the old world, such as some bearings and many parts.

Of course, the core powertrain of these machines, such as the electric motor, is still an old-world product, but our machine group is currently trying to replace it with an external combustion engine.

And the in-house production of those external combustion engines, namely the Stirling engine, is also currently underway, which has already used the iron, copper and other metal materials that you brought back from Sulu and Macau, as long as we reproduce two more second-generation mother engines, we will soon be able to build our own Stirling engine.

Boss Luo said to the crew members who looked surprised, in fact, compared with the steam engine and the internal combustion engine, it is not too difficult to manufacture, in short, we must come step by step, although there is still a process to achieve complete localization, it cannot be achieved overnight, but we are confident that this process will not drag on too long.

Boss Luo also said that now Holley has moved the other two sets of cupola furnaces and a lot of metallurgical equipment out of the cave, it seems that they want to surprise the progress, and now the brothers are installing and debugging these equipment in the industrial zone at the mouth of the Xiliu River, and then they are waiting for you to transport iron placer ore and copper ore from Timor Island in the future, and then they can start production on a large scale and make great progress......

As for the mechanical maintenance plant in front of us, if we follow this progress, the next lathe may be a completely localized machine tool - if Xiao Anzi and they install several non-ferrous metallurgical equipment in the cave, we may produce copper wire and copper wire, in that case, a lot of power machines, especially electric motors, we can also try to do it......

"Boss Luo, where is the excitement you just mentioned?"

Although everyone nodded frequently when they listened, many people did not forget Boss Luo's promise just now: there is excitement for everyone to see.

"Oh, here, do you see this machine? It's called the Iowa rifling machine, manual, for barrel rifling, we made a total of five, see? This screw is produced by our 'quasi-second generation', and it looks pretty good, right? ”

Boss Luo finally took everyone to another corner, where five shelves made of red hardwood were lined up, and there were some devices composed of steel cables, crank handles and screws, which at first glance did not seem to be very complicated.

"That's it...... Is it just like that? ”

"yes, put the barrel here, and pull it like that......"

Boss Luo immediately picked up an iron barrel removed from a Dutch flintlock pistol and began to demonstrate.

"Not bad......

"Is that what you do?"

"It looks like a simple ......"

"It's just that you have to pay attention to the balance."

"But, Boss Luo, where is the excitement you keep talking about!?"

There were still people in the crowd who persevered and asked.
